These 3/4-inch diameter balls produce a glowing tiny white LED light that fades on and off slowly. Collectively, they produce a moving firefly or fairy light effect that is absolutely unique! Place them everywhere around your venue; in the garden, hanging from trees, shrubs, or ceilings, and even in water features where they will float. They also look great in floral arrangements, table centerpiece designs, and as Christmas tree ornaments. Wire ornament hooks, small paper clips, or fishing line can be attached using the small recessed hook. Package contains 10 berries. Batteries are included and replaceable.
